Hercules Impact Wrench 12V



Easy, fast way to undo and tighten wheel nuts or other tight fasteners on any 4WD.

Every 4WDer should keep one in your vehicle. These devices are really popular.

The Hercules 12v Impact wrench uses a specially developed centrifugal two way clutch system. It can be powered from a 12v cigarette lighter or direct from a 12v battery.
